Throughout the 35 years of motor vehicle production, the De Dion Bouton company made regular changes to the specifications of the vehicles produced, but the presence of the same key personnel at the helm of the company throughout this period ensured that the changes were gradual. In overall terms, the company was conservative and some of the earliest innovations, including the De Dion rear axle were present on an extensive range of models for more than twenty years.
The development of the various models has been broken down here into different chronological periods, and within each of these the different engine configurations are covered separately. Further details on all types of vehicles can be found in the volumes prepared by Surrenden Press (surrendenpress.com)
